After watching the movie Gundam SEED FREEDOM, I had the fantasy that if there is a Duel and Buster that are converted to nuclear power, then there should also be a Geiz Custom that is similarly modified to be nuclear powered, and this is what I made.
The Gunpla I used were the old Geiz kit, HGCE Freedom, HG Justice, and HGCE Impulse that I had left unfinished, as well as a few joint parts from junk items.
The lifter on the back was scratched using plastic sheet and putty.
This was the first time I painted it with a refillable airbrush.
I used bottled Mr. Color and Gaia Color paints without mixing the colors.
